SOUTH SIOUX CITY, Neb. (AP) — No one was injured when a boat caught fire on the Missouri River between northeastern Nebraska and northwestern Iowa.

The fire occurred just outside the Sioux City Marina at Chris Larsen Park on Thursday night.

The blaze saw firefighters from Iowa and Nebraska respond. Officials said Friday they weren’t sure what sparked the fire.

Sioux City Assistant Fire Chief Dan Cougill says the boat was fully engulfed in flames and was floating downriver when fire crews arrived. The boat’s occupants had escaped the boat early on.

Potts says the boat was destroyed.
